Diopter adjustment compensates for differences in eyesight between the left and right eyes. In
addition to making observation through both eyes easier, this adjustment also reduces the difference
in focus when changing the objectives. Adjust the diopter setting for both eyepieces.
1 Turn each diopter adjustment ring on both eyepieces to align the edge of the ring with the
engraved line. This is the “O” position.
2 Perform steps MJ to IJ in chapter “2. Microscopic Procedure” so that the specimen is in focus
with the 10x objective.
3 Move the 40x objective into the optical path. Turn the coarse and fine focus knobs to focus
on the specimen.
4 Move the 4x or 10x objective into the optical path.
5 Turn the diopter adjustment ring on each eyepiece, not the coarse and fine focus knobs,
to bring the specimen into focus, while peering through the right eyepiece with your right
eye and the left eyepiece with your left eye.
6 Repeat steps 3 to 5 twice.
Interpupillary distance adjustment
Before adjusting the interpupillary distance, performs steps MN to KE in chapter “2. Microscopic
Procedure” so that the specimen is in focus with the 10x objective.
Adjust the interpupillary distance so that the view field for each eye is at the same position on the
specimen.
Doing so will make observation through the binocular eyepiece with both eyes easier.
